Yup that's Your list.

Still shows the p4-clockmod, is that right or should it say the other 1?

[AndrzejL]

This means that speedstep-lib will not work with Your CPU. Try next one till You exclude all of them or till one works.

I am not even sure any other then p4-clockmod will...

[redjama]

ok, well some of them wont even let me modprobe them, say some type of error

Code: [Select]

[root@localhost home]# modprobe speedstep-smi
FATAL: Error inserting speedstep_smi (/lib/modules/2.6.38.8-pclos1.bfs/kernel/arch/x86/kernel/cpu/cpufreq/speedstep-smi.ko.gz): No such device

[AndrzejL]

That's correct. They are designed for another type of CPU. If they modprobed on Your CPU... I would run away ...

It checks for a certain type of CPU and if it's found and if it won't break the machine - it will modprobe. If CPU type is incompatible - no such device error will occur. It's like trying to configure a banana with an mango driver... There is only one type of driver for mango and there are one of two for banana. So You can try modprobing banana drivers for Your banana CPU but the mango drivers are sure not going to work. Now some banana drivers will work only for some bananas and some banana drivers have limited options available due to the type of banana.

Ok well I went through all of them only 2 didnt come up with the error but didnt show up in the cpufreq-info only the p4-clockmod.  So im assuming im stuck with it and the rediculous heat and battery drain due to it.  Sux 

[AndrzejL]

It does indeed... Sorry to hear it. I did the best I could to help You.

You could always try the laggy powersave mode... Bit slower but no heat and no battery draining. Maybe more googling will give You some other ideas.

Regards.

how would i set the script up in the power profile to run the powersave governor when unplugged?  It ha to have rot permission to apply it.  So how would I write the script to allow it??

[redjama]

Where in PCC is the cpufreq setting to check off???

[Texstar]

Where in PCC is the cpufreq setting to check off???

System -> Manage System Services to start at boot.

[redjama]

OK well thank you for everyones help here.  Im only able to use either powersave or performance.  I guess ill be using the power save to try and cool the laptop down some.  Thanks again

[redjama]

OK well the start at boot was checked, i changed the gov to the powersaver and did a reboot.  The governor did not aply automatically, I had to go into the pcc and click start. Not sure why it didnt load at boot.
